A practical operating guide to what clients typically need before implementing bank APIs, host-to-host connectivity, ERP/TMS integration, or digital treasury tools. This page is designed to reduce delays and rework.
Five things that prevent most failed or delayed connectivity projects.
Cover initiation, approvals, status, statements, reconciliation, and exceptions before design starts.
Treasury, IT, security, ERP/TMS, and operations each need a clear accountable owner.
Weak IAM planning is one of the fastest ways to create delay and audit friction.
Automation fails quickly when payment IDs, statements, and exceptions do not line up.
Rejected payments, retries, cutoffs, and return workflows decide real operational readiness.
ERP integrator, industry use cases, and legal review triggers.
Use this for kickoff. Then use the detailed table below for planning.
| Area | Requirement | Typical client owner | Common gaps | Implementation impact |
|---|---|---|---|---|
| Business | Use case definition + success metrics | Treasury / CFO sponsor | Unclear scope (initiation only, no status/recon) | Scope drift and rework |
| Governance | Named owners and decision rights | Program manager | No single accountable owner | Delays and conflicting requirements |
| IT | Reference architecture + connectivity pattern | Enterprise architecture | Point-to-point integration without resilience plan | Operational risk and outages |
| Security | Authentication, secrets, logging, key rotation | Security / IAM | Secrets in code; weak audit logging | Security findings and go-live delays |
| ERP/TMS | ERP/TMS readiness + integration ownership | ERP/TMS owner | Connector assumptions not validated | Connector rework, timeline slips |
| Data | Payment status + statement mapping | Treasury ops + data | No canonical IDs or mapping rules | Reconciliation breaks; exceptions spike |
| Operations | Exception handling and investigations workflow | Treasury ops | No RACI for breaks and repairs | Unplanned manual work |
| Testing | Test plan, environment access, certification steps | IT delivery lead | No end-to-end test coverage | Production defects |
| Change | Training and cutover plan | Change manager | Approver workflows not trained | Controls failure risk |
| Regional | Market-by-market account structure and rules | Treasury + regional leads | Assuming one-country rules apply globally | Compliance and operating model friction |
Downloadable outline suggestion: convert this checklist into a kickoff worksheet (one page) and a detailed RACI (two pages). This site does not generate files automatically.
Each item includes what it means, why it matters, ownership, common gaps, and impact.
Write the full flow map first so the project is not scoped as “API only” while reconciliation stays manual.
Map initiation, approvals, status, statements, reconciliation, and exceptions before design starts so the project does not stop at "connectivity only."
Connectivity needs a RACI for approvals, entitlements, breaks, and support before go-live.
Decide who approves, monitors, fixes breaks, and owns bank-side admin changes before go-live so control gaps do not turn into manual work.
Many delivery issues come from ERP constraints, missing fields, or connector assumptions rather than from the bank.
Confirm the ERP or TMS can create payments, store IDs, ingest status and statements, and support the target approval flow before the bank build begins.
Authentication, secrets, logging, and access-review design should be settled before build starts.
Lock IAM, secret handling, key rotation, audit logging, and entitlement governance early because security review is one of the fastest delay points.
Real readiness comes from rejected payments, retries, timeouts, and statement/reconciliation test cases.
Test rejections, retries, returns, reconciliation, and cutover support, not just the happy path, because treasury failures usually show up at the edges first.
Payment IDs, status codes, statement fields, and return reasons need a canonical mapping before automation is trusted.
Define one mapping for IDs, statuses, remittance fields, statements, and exception routing so "automation" does not still require daily manual reconciliation.
